FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 632,320, datedSeptember 5, 1899.

Application filed March 10, 1899. Serial No. 708,515. (No model.)

To all whom, it may concern:

Be it known that we, EDGAR E. NELTHORPE and GEORGE H. WILLIAMSON,citizens of the United States, residing at J anesville, in the county ofRock and State of WVisconsin, have invented a certain new and usefulImprovement in Fountain-Pens, of which the following is a specification.

Our invention relates to fountain-pens, and has for its object toprovide a pen without a joint and of few parts and simple construction.This object we accomplish in the manner and by the means hereinaftermore fully described in detail, and particularly pointed out in theclaims, reference being had to the accompanying drawings, in which likereference-letters indicate like parts in all the figures.

Figure 1 is a central longitudinal section of our invention. Fig. 2 is asectional View of the feed-bar. Fig. 3 is a detail view of nozzle. Fig.4 is a sectional View on line a cc, Fig. 1.

Our invention consists of a reservoir-holder A, of suitable shape andmaterial, preferably hard rubber, having one end closed and the openingin the other end bored out a little larger than the rest of thereservoir to form a seat a for the nozzle B, said seat at having ashoulder a at its inner end.

The nozzle B is a small hollow cylinder of suitable material, preferablyhard rubber, reamed out at each end to form an ink-receptacle andadapted to fit snugly in said seat at, its inner end resting against theshoulder a, which prevents said nozzle B slipping back into theink-reservoir.

The feed consists of a feed-bar O, of suitable material, preferably hardrubber, divided longitudinally from one end to the heel of the pen Dinto two parts 0, which are bowed away from each other and form a springpressing against the sides of the ink-reservoir and holding the nozzle Bin place. The undivided end of the feed-bar 0 passes through the nozzleB, leaving just room enough for the insertion of the pen I) between thenozzle B and the feed-bar 0. Under the pen D when in place andon top ofthe feed-bar C is out a narrow channel 0, extending from the end of thesplit portion toward the point of the pen D and growing shallow as itapproaches such point. On the opposite side of feed-bar C a small hole 0extends longitudinally through the undivided portion of the feed-bar 0,connecting the interior of the inkreservoir with the air.

Having thus described ourinvention, what we claim as new, and desire tosecure by Letters Patent, is

1. In a fountain-pen provided with an inkreservoir, and a nozzle fittingin the open end of said reservoir, a feed-bar divided longitudinallyfrom its inner end nearly to its outer end into two parts, said partsbeing bowed apart forming a spring bearing against the sides of theink-reservoir, and said bar provided with a channel on top and anair-hole at the bottom and adapted to fit under the pen in said nozzle,substantially as shown and described.

2. In a fountain-pen, a nozzle adapted to fit in the open end of theinkrreservoir and a feed-bar divided longitudinally from its inner endnearly to its outer end into two parts, said parts being bowed apartforming a spring bearing against the sides of said ink-reservoir, andsaid bar provided with a channel on top and an air-hole at the bottomand adapted to fit under the pen in the nozzle, substantially as shownand described.

3. A fountain-pen consisting of an ink-reservoir, having its open endbored out to form a seat for the nozzle, a nozzle adapted to fit in saidseat and a feed-bar adapted to fit under the pen in said nozzle, saidfeed-bar provided with a narrow channel under said pen growing shalloweras it approaches the point of said pen and an air-hole on the oppositeside and said bar being partially divided longitudinally into two parts,said parts bowed away from each other forming a spring bearing againstthe sides of said reservoir, substantially as shown and described.

In testimony whereof we hereto aflix our signatures in the presence oftwo witnesses.
